MATCH-PLANE.

i SPECIFICATION forming part of Letters Patent No. 280,175, dated June 26, 1883. Appucmon mea Api-i123, 1883. (No model.)

To a/ZZ whom it may oon/cern,

Be it known that I, PHILIP HIGKEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Match-Planes, of which the following is a full, clear, and exact description.

lThe main obj ect of this invention is to adapt a match-plane for it to be used for the mak-` edge-thatis, it has two separate cutting edges or blades, between which `is an opening of a width which determines the width of tongue eut by the plane and the cutting-blade. The outer ofthe two, relative to the working-face of the gage upon the bottom or sole of the plane, is of a width equal to the width of said opening between the cutting -blades, or, in other words, of the width of the tongue cut by the plane, and said gage is attached to the bottom or sole of the plane-stock, so as to be' adjusted transversely thereon, and set either for the cutting of a tongue with both of the blades, or of a groove with said outer blade only of the two blades. The other blade being covered by said gage is thus put out of operative position, and all in a manner to secure a perfect iitting of said tongues and grooves so cut when joined together, and otherwise, substantially as hereinafter described.

-ln the accompanying plate of drawings the present improved plane is illustrated, Figure `1 being a side view; Fig. 2, a longitudinal vertical section through the .plane and gage; Fig. 3, a face view of the bottom or sole with gage adjusted and set for the cutting of a tongue. Fig. tis a cross vertical section on line 4 4, Fig. 1;' Fig. 5, a cross vertical section 011 line 5 5, Fig. 1, which is along the upper face of the plane orbit iron; Fig. 6, a Similar view to Fig. 5, but with the gage adjusted and set for the cutting of a groeve instead of a tongue, as in Fig. 5,.and in the preceding figures. Fig. 7 is a face view of the plane or bit iron detached, and Fig. 8 a crosssection on line 8 8, Fig. 7.

In the drawings, A represents the stock of a match-plane, B, the plane or bit iron, made of a fork shape, or, in other words, with two cutting blades or edges, C D, leaving an opening, E, between them; F, the wedge for fastening the plane-iron B in position; G, the bottoni or sole of the stock A; H, the toat or handle, and J the gage running along the length of the sole or bottom `G to the stock, and otherwise, except as hereinafter particularly described, the same as ordinary in matchplanes for cutting a tongue along the edge of a board, the width of which is determined by the width of the opening E between the itwocutting-blades C D.

rIhe cutting-blade C, which is the outer one of the two blades C D relating to the working-face c' of the gage J, in its position for the cutting either of a tongue or groove, as the case may be, (see Figs. 5 and 6,) is of awidth equal to the width of the opening E between the two cutting-blades, and in the use of this plane, as will hereinafter appear, it of itself and alone cuts the groove.

The gage, J is attachable to \and detachable from the sole or bottom G of the plane-stock A, and is secured in place by a headed screwbolt, l, and screw-nut L. V

The bolt K passes loosely through the thick- Vness of the gage .l and a slot, b, of a plate, c,

attached to and covering a recess, d, in the bottom or sole G of the plane, and the bolthead j' is in said recess, and the recess d, together with said slot b, are in a line at rightangles to the working-face u of the gage J, andofa length to allow the gage to be laterally adjusted upon the sole G of the plane for the purposes of this invention.

g (j" aretwo projecting pins,.one near cach end of the sole of the plane, and in a parallel line with the working-face a of the gage. i

m nf and a n are four holes to receive the pins g g2. These holes are situated two at each` end ofthe face of the gage which is next to the sole of the plane, and the two at each end are in a line at right angles to the work- IOO ing-face of the gage, and at a distance from each other axially equal to the width of the Y tongueM which the plane-iron B is adapted to cut, and they are otherwise so arranged that the gage can be set upon the pins g (j" of the plane either by the two holes m and m2 or by the holes a and at, in each instance one at each end of the gage, and when so set in either case have the working-face ,a of the gage in proper position for working against the face of the board to be tongued or grooved along its edge.

To set the gage J by either of its holes m and mit or a n2 upon the pins g y? of the plane, it is only necessary to first release the fasten-l ing nut and bolt K L, and then, having placed it by its holes desired upon the pins, to tighten up said bolt and nut, thus firmly fixing the gage in place. Vith the gage J adjusted and set as described, by its holes m and m2 upon the pins g g2 of the plane, the plane is adjusted for the cutting of atongue, M, as shown. in Fig. 5, and with the gage adjusted and set as described, by its holes a and at upon said pins, the plane is adjusted for the cutting ofa groove, N, as shown in Fig. G. In the first instance said setting of the gage exposes the two blades C D of the plane-iron for cutting the edge of the board, and in the second instance said setting of the gage leaves only one cutting-blade, and that the outer, C, of the two blades relative to the working-face a of the gage, and covers up the other blade, D, or, in otherwords, places it out of operative position, and as the distance between the holes m m2 and n a2 of each set of holes equals the width of tongue which the plane-iron B can cut, and the width of the outer cutting-blade, C, equals also the width of said tongue, it is obvious that by these two adjustments of the gage, together with a plane-iron having an outer cutting blade, C, and an opening between it and the other cutting-blade, D, of equal width, the same plane, using only one plane-iron, is capable of adjustment for the cutting either of atongue or of a groove, which tongue and groove, when cut, will fit each other and secure a perfect match, of course provided boards are used of the proper thickness.

To render the gage adjustable with the substitution of plane-irons for the plane-iron B, particularly shown in the drawings-that is, plane-irons having a different width of opening E between their two cutting-blades C D, and their outer cutting-blade equal to the width of said openingand thus to render one and the saine plane capable of cutting grooves and tongues of different widths, but in each instance, with the use of any iron, secure a tongue and a groove ofthe same width when the gage is properly adjusted therefor, the gage is provided with a series of holes-such as o o2 and p jai-arranged and located and otherwise in every respect similar to the holes mm2 n a2, before described, varying only in this respect, (if it may be termed a variation,) that the transverse distance of each ofsaid sets of holes corresponds to the width of groove and tongue Y groove, s, is made in the back of the outer cutting-blade, C, of each Aplane-iron, (see Figs. 7

and 8,) to fit over the edge t of the plane opposite to that of the gage, and, as the pins g g of the plane and the setting-holes m, m2, n, and a2 of the gage are located in the drawings, the groove is along the center line of the width of said cutting-blade, but it is plain that, were either the setting-holes or the pins located differently relative to the position ofthe planeiron in the plane, the position of said groove would be necessarily changed. The pins g g2 may be on the gage and the holes m m2 n a2 in the plane, and, as is obvious, these means absolutely insure the adjustment herein described of the gage to the plane-iron used. It is plain, however, that other means :might be substituted for said pins and holes, and yet insure absolutely said adjustments of the gage.

The screw-nut of the fastening device for the gage is preferably countersunk in a recess, u, of the gage, and in lieu of the fastening device for the gage particularly described and shown others may be substituted.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
